问题
I get below error while running my web application. I had problems in configuring hibernate & spring with right jars. After i crossed that hurdle after working on it for hours, i am getting problem in hibernate datasource. The session factory and dao beans are getting initialized properly by spring but when i access method in dao i get error...

Below is my application context.xml..
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/test_amar"/>
<property name="username" value="root"/>
<property name="password" value=""/>
<property name="initialSize" value="2"></property>
<property name="maxActive" value="5"></property>
<property name="validationQuery" value="SELECT 1"/>
</bean>
<!-- Hibernate Session Factory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="packagesToScan">
<array>
<value>entities</value>
</array>
</property>
<property name="hibernateProperties">
<props>
<prop key="dialect">org.hibernate.dialect.MySQLDialect</prop>
</props>
</property>
</bean>
i use spring3 & hibernate4. It appears there is configuration error in my datasource. but i am not able to locate it.
From the server log below , i see that dao & session factory beans are instantiated properly.

Kindly assist..
回答1:
Accoording to the latest version, the method getConnection(user, password) is not supported, but hibernate should not be calling that method.
You can use the spring provided org.springframework.jdbc.datasource.DriverManagerDataSource or the com.mysql.jdbc.jdbc2.optional.MysqlDataSource from your MySQL connector package. (http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html)
回答2:
try to add the following code in hibernate property
<prop key=" hibernate.dialect "> org.hibernate.dialect.MySQLDialect </prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.connection.username">root</prop>
<prop key="hibernate.connection.password">root</prop>
</props>
回答3:
try to remove from hibernate.cfg.xml
<property name="hibernate.connection.password">your-password</property>
<property name="hibernate.connection.username">your-username</property>
回答4:
The problem with
org.springframework.jdbc.datasource.DriverManagerDataSource
is that it does NOT provides pooling! I would move to Tomcat JDBC Connection Pool. That is by now IMHO the most efficient one.
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
It requires the dependency
org.apache.tomcat tomcat-jdbc
Check documentation: https://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.html
回答5:
Try to use com.mysql.jdbc.jdbc2.optional.MysqlDataSource.
